swingarm is +2 the new frame is the same length from pivolt bolt to a-arms as a 250R, A-arm mount geometry is the same as a 250r but with more rake. 15" of travel front and back. Motor has a few tricks, aftermarket bigbore cylinder with a cr 250 reedcage, dynoed in at just over 40hp (stock is 15) its apart right now waiting for me to aquir the motivation to do a +4 mm stroke with a long rod and some porting mods.. should put it over 50hp, it weighs within 5 pounds of a stock bike.
